24 alternatives to Tolaria – Open-source macOS app to manage Markdown knowledge bases
Hey there! I am Luca, I write https://refactoring.fm/ and I built Tolaria for myself to manage my own knowledge base (10K notes, 300+ articles written in over 6 years of newslettering) and work well with AI. Tolaria is offline-first, file-based, has first-class support for git, and has strong opinions about how you should organize notes (types, relationships, etc). Let me know your thoughts!
Tolaria is an open-source macOS application for organizing and managing Markdown-based knowledge bases. Built for writers and researchers who maintain large collections of notes, it operates offline-first with… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Kalmia started as a small hobby project about two months ago, but it quickly evolved when we needed a better solution to manage our office's documentation. It has now become our go-to tool for both internal and user-facing docs. Recently, we decided to open source it, as we believe others might benefit from a lightweight, customizable documentation system like this. We're excited to see how the community can take it further, contribute, and adapt it to their own needs!

Hi HN, Nick here. We’re launching OpenKnowledge (https://openknowledge.ai/), a “what you see is what you get” markdown editor that has direct integrations with Claude, Codex, and other agents. Available as MacOS app or Web UI+CLI. Fully free/local and OSS. We built this because we wanted a Notion-like experience for writing and sharing markdown files across our team. Obsidian is the best alternative we tried, but found it doesn’t have a true WYSWIG UI and it didn’t integrate well with Claude/Codex outside of community plugins. So we built OpenKnowledge. It takes…

I shipped a wiki layer for AI agents that uses markdown + git as the source of truth, with a bleve (BM25) + SQLite index on top. No vector or graph db yet. It runs locally in ~/.wuphf/wiki/ and you can git clone it out if you want to take your knowledge with you. The shape is the one Karpathy has been circling for a while: an LLM-native knowledge substrate that agents both read from and write into, so context compounds across sessions rather than getting re-pasted every morning. Most implementations of that idea land on Postgres, pgvector, Neo4j, Kafka, and a dashboard. I…

I got tired of Claude hallucinating Swift APIs. It does a good job at Python and TypeScript, but ask it about SwiftUI and it's basically guessing. The problem? Apple's docs are JavaScript-rendered, so when you paste URLs into AI tools, they just see a blank page. Copy-pasting works but... c'mon. So I built something that converts Apple Developer docs to clean markdown. Just swap developer.apple.com with sosumi.ai in any Apple docs URL and you get AI-readable content. For example: - Before: https://developer.apple.com/documentation/swift/double - After:…

Kraa 1.0▲359Hi HN! Excited to share the public beta of Kraa – a web-based markdown editor. It's aiming to be distraction-free and has strong separation of the document's styling from the experience of writing it — while still alowing for rich customization. Example of a leaf with custom styles: https://kraa.io/kraa/examples/echolibrary Curious about your feedback in hopes of improving Kraa before the planned launch later this year.

This lets you talk to local LLMs in Apple Notes. I saw Obsidian Ollama (https://github.com/hinterdupfinger/obsidian-ollama) and thought it was handy, but I'm too lazy to migrate away from the Apple ecosystem, so I quickly hacked this together. I tend to use Notes as a scratchpad for prompts, so it's nice to do some quick inference without leaving the app. Notes doesn't really support plugins so I'm using the macOS accessibility API for reading selections and then stream responses using the clipboard (not ideal but it works).

Hi HN, Since 2019, I’ve been working on a writing platform designed for creating complex documents (e.g., theses). I personally use it for everything as it also allows to classify documents in categories so you can organize them efficiently. As of a few months ago, the app is also available in the browser, and you can now invite coworkers to collaborate on a document in real time. The app is somewhat inspired by LyX. It offers an intuitive, modern editor, but users don’t need to know any LaTeX. When it’s time to export, they can choose from a range of templates (IEEE paper, thesis, etc.). A…

Thank you for your comments, just some context: - The app is available for iOS, Android, Windows, Mac, Apple Vision Pro, and the Web. - The Web version is implemented as a Progressive Web Application that is very responsive, local first, offline first, can be installed, and is entirely free to use. - Native (hybrid) versions do not require subscription fees and have small one-time payment. - You can store your notes in Git using any Git provider such as GitHub, GitLab, or Bitbucket. However, it has the best built-in integration with GitHub. Self-hosted scenarios like Gitea are also…

Scipress is a writing platform with VS code editor built into the browser. It lets you make beautiful blog posts and programming docs with Markdown. Scipress supports code blocks with syntax highlighting, Katex, Tailwind CSS, images & videos, admonitions, popovers, blur screens, private posts, and a bunch of other cool stuff. You can also monetize via paywalls, if you want. I started this project almost a year ago to the date. This is my first time posting about it on HN. And if you're curious, I have made $0 from this project (but not for lack of trying).

Bello! Made this to help navigate the tumultuous process of navigating to a new machine on Mac when you have a number of custom utilities setup for editing particular files. This is designed to make that as easy as possible, and add some magic on top of that, like setting mailto handlers or anything else of that breed. Use XDG_CONFIG_HOME to keep it organized. Credit to https://github.com/moretension/duti for the original inspiration for the project. Happy to answer and help with whatever.
